RJ11 converter to RJ 12

[Extrme]

Hi,
I bought a Jabra headset on eBay for my work but then found yout that the headset had a RJ 12 connector and my work phone had a RJ 11. I have done a couple of stores in Sydney but none carry an adaptor. Any advice on online store or other ways to proceed?

you may have to get a telephone tech to put the right plug on the wire. there may not be an adapter. The Australian color code is different from other countries.
